RAIL-CIiAMPING DEVICE.

Application 'fi led March 21, 1924. SerialNo; 700,846.

To all whom it may concern:

Be it known that 1, JOHN' E. l\ IOGRANER,;

a citizen of the United States, residing at Harrisburg, in the county of Salineand, State of Illinois, have invented certainne'w and useful Improvements'in Rail-Clamping Devices, of whichthe following is as ecification, reference being: had tlierein to 't' to ac companying drawings.

This invention relates to a rail clamping device, and'the object of the invention is the construction of an apparatus whereby an extension of a track in a mine can be quickly and efficiently accomplished.

Another object of the invention is the construction of an apparatus employing filler members constituting tracks, together with clamping elements cooperating with the filler members in the construction on an extension of a track.

Vith these and other objects in view, my invention comprises certain novel combina tions, constructions and arrangements as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings: 1

Figure 1 is a perspective view of an apparatus constructed in accordance with the present invention.

Figure 2 is a sectional view, taken on line 22, Fig. 1, and looking in the direction of the arrows.

Figure 3 is a perspective view of the primary jaw of the apparatus, while Figure 4 is a perspective view of the auxiliary jaw.

Figure 5 is an enlarged, fragmentary view of the apparatus. I

Referring to the drawings by numerals, 1 designates the ties and 2'is an ordinary rail resting upon one of the ties 1.

In constructing an extension of a track, for instance in a coal mine, I employ two of my apparatuses but as they areduplicate in construction it will only be necessary, to

specifically describe one. When the coal has been mined beyond the end of the rail 2 and it is desired to get the coal cars close to the mined coal or ore, as the case may be, I place one filler member 3 on a tie 1 with a strong, small head 4 resting under the tread of the rail 2; head resting flat against the web of the rail. The filler member3 is provided with a web 5 and a broad base 6, which base 6. is providedwith a'flat, outer surface? that bears snug against the flat bearing face Softhe auxiliary jaw 9 (Figs. 2 and 4);

- The rail 2 rests uponthe flat face 10 of theprimary jaw 11, and this'j aw 11 is pro vided with a pointed bearing portion '12 bridging over the base of rail 2 (Figs. land 2) and bearing against the web ofsaid rail; it is to benotedthat the center of pressure is caused upon the web of the rail right at the middle ofthe head 4 of the filler member 3, thereby making a very steady and secure structure, for locking the parts 2 and 3 together, so that this extension of the roadway in the mine will be secure and not liable to become disassembled, whereby delays and loss in mining of coal and other minerals will be eliminated.

The auxiliary jaw 9 is provided with a horizontal, threaded aperture 13 that receives the bolt 14, which bolt also extends through aperture 15, of the primary jaw 11. A suitable operating wrench 16 may be placed on the head 17 of bolt 14, and any type of an operating pin, for turning a bolt,

may be placed in the aperture 18, of head 17 A horizontal, conical socket 19 is formed in the body of the auxiliary jaw 9, above aperture 13, and this socket 19 receives the conical wedge pin 20, which pin is integral .cient assembling of the parts of my apparatus.

The filler miembers 3 of my apparatus will act as rails for receivin the wheels of the car, or cars, from therai s 2, so that the cars to be. loaded can be brought up very close to the material that the cars are to be loaded with; the flanges of the car wheels traveling over the-webs 5 of the filler member 3.

My apparatus eliminates the use of spikes 0r nails, in assemlblin parts for producing an extension of a roa way, which is a great saving to the mine owner.

While I have described the preferred embodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope 2. In an apparatus of the class described,

the combination with a rail provided with a web and abase, an auxiliary jaw contiguous to said rail, of a primary jaw under said base, said primary jaw provided with a pointed bridging portion extending over the base of the rail and pressing against approximately the center of the web, a filler member provided with a broad base bearing against the auxiliary jaw, said filler member provided with a Web and with a small head having a fiat outer face bearing against the web of the rail with the pressure exerted by the pointed portion of the primary aw in approximately the middle of said head, manually-operated rotatable means in said jaws for drawing the same together and holding them in their assembled. position, and a socket and pin structure formed upon said jaws for assisting in assembling and holding the jaws together, substantially as shown and described.

In testimony whereof Ihereunto aflix my signature. I

JOHN E. MoGrRANER.
